First time posting here. These shut off valves below the bathroom vanity were very hard to close, I ended up bending them to shut them off. How hard would it be to replace these? I saw videos about cutting the pipe etc. but these are vertical and not very common. They seem to be already close to the ground, would like to have them accesible above the floor of the new vanity. Any help is appreciated.

They look like they're threaded on.
I hate fucking plumbing. I'd be afraid of snapping the pipes or something stupid because they're old and fucked. Last time I had to fuck with my plumbing to install a new faucet I accidentally broke the PVC line because it was old and brittle as fuck and it was a fucking nightmare to fix.

>> No.1882398

>>1882391
What does threaded on mean, could that be a simple replacement or do I need to waste at least $100 for a plumber to assess then rape my wallet cause im unexperienced. Ive done many projects in the house but these probably werent shut off for many many years.

>> No.1882399

You are better off cutting below shutoff and putting in a sharkbite shutoff. Old plumbing is fucking aids I hate dealing with old corroded on shit because I would really rather not snap something off into a wall. Sharkbite isn't ideal btw but it is the easiest option

It's like a nut and bolt kind of. Pipe is threaded shut off has threads you screw it on there. Old ones are a bitch to get off.

I personally would just cut it and sharkbite. I was doing some work for a friend last night and ran into it. I didn't feel confident about really putting force on a 30 year old shut off on copper piping that was sticking out 2in from the wall. Said I'd replace the faucet and get it hooked up to the old one or go get some different shutoffs than what I brought and would replace them as well. Your easiest way is to sharkbite on and proceed as normal. Could run cpvc from the sharkbite and glue on a thread adapter to use the no burst metal lines to hook up the faucet. It looks like you have pulled the vanity already?

>> No.1882442

>>1882433
Yes, the vanity was removed. I have a new one and new faucet as well, ill finish painting the bathroom tomorrow but before installing the new vanity these valves definitely need to be updated/replaced. Looking for the best option and possibly DIY before calling the plumber.

Also will put new vinyl planks after vanity is installed

Sharkbite good idea.
Cut the tube with a tubing cutter, not a hacksaw.
Those old fittings could be threaded or sweated on. Odds are they have become so tightly attached you will twist the pipe out of the next joint down (usually an elbow). Also great time to replace those corroded bells..
Now they do make a brass valve that has a compression fitting. If you want to stay with brass. Or you could sweat on a new one the old fashioned way.

>> No.1882450

>>1882446
Looks like galvanized steel pipe to me. Could be wrong. Don't mix metals if it is. Steel to steel, copper alloy to copper alloy (copper, brass, bronze). If you mix metals you will get corrosion very quickly. If you absolutely have to mix metals than connect them with a dielectric union. It will prevent corrosion.

>> No.1882559

>>1882389
The water lines coming up through the floor may be threaded brass, if this is the case a shark bite is not going to work. Could you take another picture from a little lower angle looking up at the connection to the valve? Or is this piping visible from an unfinished basement below? If those are brass or galvanized lines you will need to thread the old valves off and thread new ones on. Let’s get a little more information before you start cutting into anything.

>> No.1882617

>>1882389
Looks like its threaded. Two pipe wrenches and a torch will make it easy to take them off.

Drain the water from the system, open the valves. Heat the valves where they thread onto the threads. Use pipewrench to turn off with the other pipewrench to backwrench the pipe. I do a lot of piping at work, 150 psi steam. Pipes are always old and rotted out, a torch is your friend for hard to remove fittings. For unions, a hammer is your friend. With areas with no unions and in the middle of nowhere a zipdisk (angle grinder).

When installing new valves, don't cheap out and use that cheap thin white teflon tape. It's just not worth it, spend a little extra for the thicker orange tape. Wrap 2-3 times around going in the same direction that the fitting will thread on. Then if you want to really make sure it won't leak put a bead of pipe dope on it. Trust me, It's a pain in the ass to have to redo everything because of a tiny leak at the threads.

>> No.1882634

Lots of people saying shark bites. If you use them, make sure to secure the pipe so it can't bend in the fitting. Make sure it's somewhere accessible, too.

>> No.1882674

>>1882634
Also if you use them, make sure those water lines are actually copper before you make any big plans to hack into them and slap on a SB.

Hello i am a plumber, those are extension stops. Your best bet is to rebuild them i think.

Industrial mechanic here. Pipe dope is love and unlike tape permits backing off part of a turn and realignment while tape gets trashed instantly. I just use dope as that's it's intended purpose and it predates Teflon let alone tape.

Here is the straight stop valve.

>> No.1883477

>>1883446
That is soldered on. You should be able to heat it up, pull it off with a pair of channel locks, clean the end with sand cloth, and install a new compression or sweat valve. If you don’t like the sound of that, you should be able to shark bite it, just make sure the ends of the pipes are cut clean and all paint and debris is sanded, if the o-ring tears it will leak.

Small spot of solder ... DONT TRY UNSCREWING THE VALVE FROM THE PIPE. Its sweated in place and wont unscrew. Grab a pipe cutter and sharkbite fittings.

Plumber came and replaced the extension tube, it was all one solid piece. He replaced with 1/2 inch copper. Thanks for everyone who said to cut and sharkbite, you all are terrible. Good news is everything was cleaned and he even installed the vanity and faucet etc. 2 hours of work.
I also understand plumbing more now, he said this mistake couldve happened to anyone.
